javascript - JSON: Add pointer -

i have automatially made json looks like:

{     "node_id_1": {         "x": -87,         "y": 149     },     "node_id_2": {         "x": -24,         "y": 50     },     "node_id_3": {         "x": 55,         "y": -32     } } 

i have problems access specific node_id x , y values. idea automatically add "id:" before e.g. "node_id_1" , flatten array. give me hint how add "id:"? or there elegant way access ids? thank lot! best regards

a possibility using es6, if attempting do? perhaps clarify question further description , examples of code using trying access data?

function clamp(value, min, max) {    return math.min(math.max(value, min), max);  }  const jsonstring = '{"node_id_1":{"x":-87,"y":149},"node_id_2":{"x":-24,"y":50},"node_id_3":{"x":55,"y":-32}}';  const javascriptobject = json.parse(jsonstring);  const mysortedarray = [];  // depending on preference use array#map here  // instead or create iterator object.  (let key of object.keys(javascriptobject)) {    mysortedarray.push({      id: key,      value: object.assign({}, javascriptobject[key])    });  }  mysortedarray.sort((a, b) => {    // overkill, precise.    return clamp(math.trunc(a.id.localecompare(b.id)), -1, 1);  });  document.getelementbyid('out').textcontent = json.stringify(mysortedarray, null, 2);  console.log(mysortedarray);
